Corundum var. ruby - marble quarries Prilep, North Macedonia
 Former Robert Scheck Collection
 Intense pink ruby on a marble matrix.
 Rubies from Prilep are known for their typical pink color, but it's extremely rare to find this intense. In addition to its color intensity, this crystal impresses with its 3 cm diameter. A 1 cm crystal sits beautifully freestanding on the main crystal.
 The dolomite marble near Prilep contains numerous calcite veins with idiomorphic corundum and rutile crystals.
 Flawless collector's item from Macedonia.
